Hi!
I found this thread in the mail archive and I have a question to this thread. How many pstn gateways can I handle with this failover statement ? Is there a timeout I have to keep in mind, or can I put gateways as many as I have ??? For example. I have one SER Server and 10 PSTN gateways and on every gateway, 4 PRIs. Can I configure the ser server so that the server ask one after another until he found a gateway which accept his call ?
The last question is, which isdn features can I use with SER ? I mean can a Ser user make auto hold or call park or something like that ?
Thanks in advance, Ahmad
You could not, because ser does not know which PSTN gateway is less loaded. What you can do is to forward all calls to one of the gateways and when the gateway refuses the call then you can try the other one. This can be done using failure_route statement in the configuration file.

Hi Ahmad,
you can do it a more elegant and scalable way by using the dispatcher module which implements a load-balancing logic. you will not have "less used" selection, but a "uniform" one...better than serial forking approach.

Do you have an example ? What do you mean with uniform ?

Any ideas belonging this issue ?

see "modules/dispatcher/doc/dispatcher.cfg" - it's an example posted by Daniel, the author of the module.
What do you mean with uniform ?
more distributed :)

this are mostly UAC features. SER is mainly a PROXY and ,AFAIK, there are no such features.
Hi Marian,
thanks for your help.

I have read the documentation for UAC under this link: http://www.voice-system.ro/docs/uac/index.html I could not find anything which could help me. Is UAC a Interface for another software/module or something like that. Do I need another software in order to provide isdn features ?
Thanks in advance, Ahmad

there is lcr module in CVS HEAD that can handle any number of gws. you can also configure a couple of timeouts.
